Fraternal squirrel

The fraternal squirrel, Sundasciurus fraterculus, is a species of rodent in the family Sciuridae. It is endemic to Indonesia and is found only in the Mentawai Archipelago, on the islands of Siberut, Sipora, North Pagai and South Pagai, which lie off the west coast of Sumatra. Oldfield Thomas described it in 1895, and it belongs to the genus Sundasciurus, which it shares with Brooke's squirrel and the Davao squirrel. The IUCN Red List assesses it as Vulnerable. The sources read for this entry record little else about its ecology or behaviour, so its habitat, diet and population trend are not yet documented here.
